need some help!

i was diagnosed over a year ago with ibs by my doctor and have been referred to just about everyone from dieticians to phsyciatrists. ive tried a lot of herbal remedies aswell as being prescribed different things from my doctor but have not managed to get my ibs symptoms under control.
i have various symptoms, the main one being a very active and noisy stomach, which i get everyday but worst in the morning and through the night..seem to be better during the day.
does any one else have similar symtoms? this has caused me a lot embarrassment to the point where i have panic attacks if im around people.
can anyone suggest anything i could take to help with this?...many thanks
